To all whom it may concern:

Be'it known that I, ANDREW EPPLER, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Sole-Laying Machines; and I do hereby declare the following to be a full, clear, and exact descripothers skilled in g tains tomake and use the same. V

Thepresent invention relates .to machines for laying soles upon boots and shoes and the art to which itapperlS.Sl10W11 more particularly in connection with a machine of the type disclosed in the patent to Davenport No.1,066fl73, July8, 1913. a I

This type of machine is provided with a yielding pressing pad which is designed to force all portions of 'a shoe sole intocontact with a shoe bottom upon which the sole is to be laid. For this purpose the pressing face ofthe pad iscurved to correspond'to the general contour of the shoe bottom and is provided with oppositely disposed shoulders or projections adapted to engage with the shank portions of the sole and force the latter into contact with the. shoe bottom. As these raised portions or shouldersengage the sole with the greatest pressure it follows that there is a tendency during the contin- HQdCOPBIRlllOIl of the machine to cause-a de pression of the shoulders and aconsequent flattening out of the pad so t-hat'the latter does not perform its function of shaping the sole to the shoe bottom, especially at the shank. V

- The ..object of the present invention is to 2 improve sole laying machines of the type yielding pressing described embodying apad insuch a-mannerthat the range of usefulness and efliciency of thepadis greatly increased. Accordingly with this object in view a feature of the invention consists in' the combination in asole laying machine provided zwith a yielding pad having a curved pressing'face corresponding tolthe' contour of a shoe bottom, of means cooperating withilthe pad beneath a projecting shoulder and arranged to raise the shoulder fromt-he surfacejof the pad. -This'construction not only permits the restoration of the pad to its initlal shape after it has become flattened out through long continued use,

but provides for the requisite adjustment of the pad when operating upon different styles of shoe bottoms in which the shape to'be imparted to the sole may vary' widely. I lnthe simplest and most eflicient form of the invention which has yet been devisedan adjusting wedge is the pad opposite a moved to'raise face of the pad.

In the accompanying shoulder and may be l The sole laying machine'is provided with a shoe supporting jack a cooperating press- 7 ing pad and actuating mechanism designed to relativelymove the jack and pad to apply a direct pressure to the shoe sole and shape the sole approximately into conformity with the shoe bottom. The of rubber and is sufliciently yielding to permitthe pad to accommodate itself to irregularities in the shape of the shoe bottom or slight discrepancies between the shape of the shoe bottom and the shape of the pad. As shown clearly in the drawing, the pad comprises a body portion 10 having a curved pressing" face 12 shoulders 14 adapted to engage with and press down opposite margins of the sole at the shank, the heel seat ofthe sole resting substantially on the portion 15 of the pad.

It is desirable that the shoulders 14 pad shall have As these raised portions of the pad bear upon the sole with a located in the" side of drawings illustratmg the preferred form of the invention, Fig-- of the improved pad pressing pad is made.

greater pressure f'th'an certain other portions of the pad; the tendency of the'pad is to shank, is not properly shape'd'to the shoe bottom. This disadvantage'is overcome in r 7 i the sole, especially at; the

the-present invention through the use ofan adjusting wedge supported behind the shoulder orfother raised portion of the pad and having provision for adjustment to force the shoulder outwardly with respect to the surrounding surface of the pad. In the illustrated embodiment of the invention a pair of wedges are received in opposite sides of the pad behind the shoulders 1st and are supported upon a single rod passing through the pad. These wedges have provision for adjustment relative to the rod to cause them to enter the pad, forcing the shoulders outwardly from the surface.

A pair of adjusting wedges 17 enter correspondingly shaped recesses formed in opposite sides of the pad behind the shoulders 14. These wedges are supported upon a rod 18 extending transversely of the pad between the upper and lower surfaces and having adjusting nuts 20 threaded thereon which engage with the wedges and serve to force them into the pad to spread the surfaces on opposite sides of the wedges. From an inspection of the drawings it will be observed that each wedge is elongated and is provided with opposite curved surfaces 21 converging to a knife edge 22 and shaped approximately to the curvature of the shoulders 14. In order to facilitate an independent adjustment of the wedges and permit one of the shoulders to be forced out from the surface of the pad more than the other, means are provided for retaining the rod against movement relative to the pad. To this end a retaining plate 24 is received in a longitudinal slot 25 formed in the pad and is connected to the rod 18 by oppositely disposed collars 26. With this construc tion either wedge may be forced to enter the pad by a simple manipulation of the adjusting nut. It will be noted from an inspection of the drawings that the retaining plate 2a is provided with a vertical slot 27 which embraces the adjusting rod 18 to permit the convenient insertion of the plate aftgr the rod has been assembled within the pa It will be observed that this construction not only permits the restoration of the shoulders to their original. form if they should become flattened out through long continued use, but enables the curvature of the pad to be varied if so desired for operation upon different styles of shoe bottoms. For example, if the pad is designed particularly for the laying of soles upon shoe bottoms having a substantially flat shank they may likewise be adapted for laying soles upon shoe bottoms having a well rounded shank through the proper adjustment of the wedges to secure a greater projection of the shoulders from the surface of the pad.

While it is preferred to employ the specific construction and arrangement of parts shown and described, it will be understood Copies of this patent may be obtained for five cents each, by addressing the that this construction and arran ement is not essential except so far as speci ed in the claims, and may be changed or modified without departing from the broader features of the invention.

The invention having been described, what is claimed is:

1. A pressing pad having a yielding body portion provided with a curved pressing face, and means embodied in the body portion of the pad for varying the curvature of the pressing face.

2. A pressing pad of yielding material having a curved pressing face provided with a projecting shoulder adapted to engage with the shank portion of a sole, and means embodied in the pad for varying the projectiog of the shoulder from. the surface of the pa 3. A pressing pad for sole laying machines comprising a yielding body portion having projecting shoulders adapted to engage with opposite sides of the shank portion of a shoe sole, a pair of wedges received in opposite sides of the body portion of the pad behind the shoulders, and means for adjusting the wedges to vary the projection of the shoulders from the surface of the pad.

1. A pressing pad for sole laying machines comprising a yielding body portion having a curved pressing face, an adjusting rod passing through the pad, a pair of wedges supported upon opposite ends of the rod and received in opposite sides of the pad, and means for adjusting the wedges relative to the pad.

5. A pressing pad for sole laying machines comprising a yielding bod portion having a curved pressing face, a rod extending across the body portion of the pad, a retaining member connecting the rod with the body portion of the pad to prevent endwise movement of the rod relative to the pad, a wedge supported upon the end of the rod and received in one side of the pad, and means for adjusting the wedge lengthwise of the rod. 1

6. A pressing pad for sole laying machines comprising a yielding body portion having a curved pressing face provided with oppositely disposed shoulders to engage the shank portion of a shoe sole, a rod extending across the pad, a wedge received in the side of the pad behind each shoulder, and comiections between the wedges and rod for independently adjusting the wedges relative to the pad.
